The sale prices are back through February 25, 2018. The price is $69 and you can order through this link (disclaimer: that's an affiliate link to Ancestry; if you purchase a test, you don't pay a penny more, but WikiTree gets a pittance--literally--of the transaction to help keep all things Tree free).
Like airline prices, if one goes on sale, others often follow suit. So if you're looking for a different type of test, or one through a different company, keep your eyes open. Other sales may be coming soon.
